UNITED STATES PATENT GFFICEQ IVINFIELD H. ELLIS, OF ARGENTA, ARKANSAS.

CUT-OFF AND DRAINAGE APPARATUS.

Application filed February To all whom, it may concern:

Be it known that I, W'INFIELD H. ELLIs, a citizen of the United Statesof America, and a resident of Argenta, Little Rock, county of Pulaski,State of Arkansas, have invented certain new and useful Improvements inCut- Off and Drainage Apparatus, of which the following is a full andclear specification, reference being had to the accompanying drawings,in'which Figure 1 is a side elevation of my apparatus, showing itinclosed in a casing or box set in the ground; Fig. 2, a plan view withthe box removed, and Fig. 3 a horizontal sectional view showing therelative positions of the supply and drain cocks.

The object of this invention is to provide a simple valve apparatuswhich will insure the complete draining of both the cold-water and thehot-water systems of a building when the cold water is cut off from thehouse system, whereby freezing in either the cold Water system or thehot-water system in the house is avoided, as more fully hereinafter setforth.

To the accomplishment of this object and such others as may hereinafterappear, the invention consists of the arts and combination of partshereinafter fully described, and particularly pointed out in theappended claim, reference being had to the accompanying drawings,forming a part of this specification, in'which the same referencecharacters designate like parts throughout the several views.

Referring to the drawings by reference characters, A designates acoupling or casing in which a vertical turn-plug or cook a is mounted,the upper end of this plug proj ecting above the casing and beingprovided with a radial arm a. This arm a, vibrates between shoulders a,formed on the top of the casing, and projecting inwardly from the casingof the valve is a horizontal arm a The letter B represents a coupling orcasing similar to casing A and which is provided with a verticalturn-block or cock I), which is provided with the usual mainwater-passage through it and also a drain-port I), which is adapted toput the house end of the casing or coupling in communication withSpecification of Letters Patent,

drain-port I) when the cock is closed. The upper end of the plug isprovided with a squared socket with which may be engaged a suitableoperating key or wrench K for opening and closing the plug. This plug 1)is provided with a radial arm I), which vibrates between shoulders I)"on the top of the casing to open and close the cock. This casing B isalso provided with a lateral arm 1), extending inwardly and overlappinga similar arm (1 carried by the casing A. These two arms are rigidly butdetachablv connected together by screw-bolts 0;, which pass throughregistering holes in the arms.

The ends of the arms a/ and I) are connected by a link C and pivotscrews or bolts 0 and 0, whereby when the supply-plug I) is opened thedrain-plug a is closed, and vice versa. The pipe F from the main isconnected to one end of the coupling B and a pipe G to the other end,this latter pipe being connected. to the fixtures in the building. Thepipe E, leading from the fixtures, is connected to the inlet end ofcoupling A, and a pipe D is connected to the outlet end of saidcoupling. It will be observed, therefore, that when plug 5 is closed thesystem connected to pipe G will be drained through I) and. I), and thehotwater system connected to IE will drain out through plug a and pipeD. The casing or box II is notched at its 'lower end, so as to besupported on the projecting ends of the pipes, and, as shown, this boxmay be made in halves, and it will be provided with a suitable openingfor the insertion of the operating key or wrench K. The drainage-watermay be permitted to soak away into the surrounding sand or earth, or itmay be conducted to a sewer or drain, as is obvious.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is

In an apparatus for the purpose set forth, the combination of a valve orcock inserted in the supply-pipe, said cock being provided with adrain-port and with a lateral arm and means for restricting the movementof the arm, the casing of said cock being provided with a rigid lateralarm, another valve or cock arranged opposite the aforesaid cock L andinserted in the drainage-pipe from the heating system, the plug of thispipe being In testimony whereof I hereunto affiX my provided with aradial arm, the casing of signature, in the presence of two Witnesses,this cock being provided With a rigid lateral this 26th day of January,1907.
